Overview
The DHP-9162 Benchtop Electrically Heated Constant-Temperature Incubator is a precision-engineered, microprocessor-controlled environmental chamber designed for stable, repeatable thermal conditioning of biological samples in academic, agricultural, and industrial life science laboratories. Utilizing resistive film heating elements integrated with mirror-finish stainless steel interior walls, the unit achieves rapid thermal response and minimal thermal gradient across its 160 L working volume. Its control architecture is based on proportional-integral (PI) temperature regulation, delivering a uniform thermal environment with ±0.5°C spatial uniformity under no-load conditions at 20°C ambient and 50% RH — consistent with ISO 15195:2013 guidelines for incubator performance verification. The chamber operates within a defined range of RT+5°C to 65°C, making it suitable for mesophilic microbial culture, enzyme activity assays, cell line maintenance, and short-term seed or tissue storage where active humidity control is not required.
Key Features
- Microprocessor-based digital controller with 0.1°C temperature resolution and programmable timer (1–9999 minutes), enabling unattended operation and protocol reproducibility.
- Dual-door design: outer insulated door with magnetic seal and inner transparent tempered glass door for real-time visual monitoring without thermal disturbance.
- Electropolished 304 stainless steel interior chamber with seamless corners, facilitating cleaning, decontamination, and compliance with GLP laboratory hygiene standards.
- Independent over-temperature safety cutoff system (optional configuration), automatically interrupting power when user-defined limit thresholds are exceeded — supporting risk mitigation per IEC 61010-1 safety requirements.
- Optimized airflow management via rear-mounted heating element and passive convection path, minimizing turbulence and ensuring low-vibration sample stability.
- Compact benchtop footprint (790 × 630 × 810 mm) with load-rated shelving (2 standard trays, 30 kg max per shelf), compatible with standard Petri dishes, flasks, multiwell plates, and culture tubes.
Sample Compatibility & Compliance
The DHP-9162 accommodates common life science containers including 100–250 mL Erlenmeyer flasks, 90 mm Petri dishes, T-25/T-75 cell culture flasks, and 96-well microplates. Its non-humidified chamber relies on ambient lab humidity (20–50% RH typical), rendering it unsuitable for long-term hygroscopic sample storage or CO₂-dependent cultures. While not certified to ISO 13485 or FDA 21 CFR Part 11, the incubator meets general-purpose laboratory equipment requirements under GB/T 23792–2009 (Chinese national standard for electrically heated incubators) and supports audit-ready documentation when used within institutional SOPs aligned with ISO/IEC 17025 quality systems.
Software & Data Management
The DHP-9162 operates via embedded firmware with no external software dependency. All operational parameters — setpoint, actual temperature, elapsed time, and timer status — are displayed in real time on a high-contrast LED interface. Data logging is not natively supported; however, optional analog output (0–5 V / 4–20 mA) can be interfaced with third-party SCADA or LIMS platforms for basic trending. For regulated environments requiring electronic records, integration with validated external data loggers (e.g., compliant with ASTM E2810–18 for temperature mapping) is recommended to satisfy GxP traceability expectations.
Applications
- Maintenance of bacterial and fungal stock cultures (e.g., E. coli, Saccharomyces cerevisiae, Aspergillus niger) at optimal growth temperatures.
- Enzymatic reaction incubation for kinetic studies, ELISA plate development, and antigen-antibody binding assays.
- Agricultural seed germination trials and plant tissue explant pre-incubation prior to sterile transfer.
- Quality control testing of pharmaceutical excipients and medical device packaging under accelerated thermal stress.
- Supporting ISO 8573-1 compressed air testing protocols requiring stable 37°C exposure of microbiological sampling media.
FAQ
Does the DHP-9162 include active humidity control?
No — this model maintains only temperature stability. Relative humidity is ambient-dependent and unregulated.
Is the incubator suitable for use with CO₂-sensitive cell lines?
No — it lacks gas-tight sealing, CO₂ injection ports, and pH-buffered atmosphere control; use only for non-CO₂-requiring organisms or biochemical assays.
Can the over-temperature protection be disabled?
No — the independent safety cutoff is hardwired and non-bypassable in factory-configured units to ensure continuous compliance with electrical safety directives.
What calibration documentation is provided?
A factory-issued temperature verification report (at 37°C and 50°C, single-point) is included; full ISO 17025-accredited calibration requires third-party service.
Are replacement shelves available separately?
Yes — optional reinforced stainless steel shelves (500 × 500 mm) and polymer-coated wire racks are stocked by authorized distributors for extended durability and chemical resistance.
